As well as this they need to be trained in the use of the Hare Psychopathy Checklist - Revised. These people should have degrees in medical or behavioral science, be certified to diagnose mental disorders (e.g., psychiatrists and psychologists) and be experienced in working with criminal populations. The results of this test have far-reaching implications for the patient, and so its use is confined to a small group of people. Therefore, it is also being used to assess the probability of a criminal re-offending as well as determining the length of sentence and whether or not treatment is advised.

It is also considered to be the most accurate predictor of violent behavior that we have. It is a complex clinical tool that is only used by experts in the field.

The Robert Hare Psychopathy Checklist - Revised is considered by clinicians and researchers worldwide to be the 'gold standard' in assessing psychopathy.
